QMS Series Single Ended Mixers
(PDF available)

Characteristics
  • General Purpose

  • Broad or Narrowband

  • Low Cost/Moderate Performance

Product Description

QuinStar Technology's QMS series single ended mixers are available in either narrowband or broadband fixed tuned configurations. The narrowband mixers are tuned for optimum performance at a specified frequency and have lower conversion loss. The broadband mixers are tuned for operation over a full waveguide band. Both versions are offered in waveguide bands from 18 to 110 GHz, utilize a single diode and have a common RF/LO input port (no diplexer).

Single ended mixers are well suited for general laboratory test setups that require conversion of millimeter-wave signals to IF signals. For applications requiring better LO to RF isolation or lower conversion loss, refer to QMB series balanced mixers. For other applications harmonic mixers (series QMH), spectrum analyzer mixers (series QMA) and upconverters (series QMU) are available.
